本文研究了自由粘附在刚性壁面上的开放流体膜的平衡问题。我们得到一个协变方程，确定的平衡形状的自由膜时，一般的自由能泛函来描述其弹性。然后将该方程与文献中已有的脂膜方程进行比较。开放膜的特征在于其具有边界，该边界也可以是粘性的。这是本文的主要目的是达到的平衡条件施加在粘性边界。特别是，这些条件被施加到一个简单的问题，该模型的粘附膜的轴对称的配置文件。对于该示例，我们还能够研究粘合剂边界的稳定性。
We study the equilibrium of an open fluid membrane free to adhere to a rigid wall. We obtain a covariant equation that determines the equilibrium shape of the free membrane when a general free–energy functional is employed to describe its elasticity. This equation is then compared with that already available in the literature for lipid membranes. The characteristic feature of an open membrane is that it exhibits a border, which could also be adhesive. It is the main objective of this paper to arrive at the equilibrium conditions to be imposed on an adhesive border. In particular, these conditions are applied to a simple problem, which models the adhesion of a membrane to an axisymmetric profile. For this example we are also able to study the stability of the adhesive border.
